CROSS-REFERENCE TO RELATED APPLICATION

This application is continuation of U.S. application Ser. No. 16/731,170 filed Dec. 31, 2019, which is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0002398, filed on Jan. 8, 2019, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entirety.

BACKGROUND 1. Field

Various embodiments of the disclosure relate to an image display device and an operation method thereof, and more particularly, to an image display device capable of conveniently setting a multi-brand remote (MBR) controller that controls the image display device and a peripheral device connected to the image display device, and a method of operating the image display device.

2. Description of the Related Art

Image display devices have functions of reproduce images that users may view. For example, users may watch broadcasts through the image display devices. The image display devices display broadcasts selected by the user from among broadcast signals transmitted from a broadcasting station.

Moreover, smart televisions (TVs) providing a variety of content in addition to broadcasting functions have been developed. Instead of passively operating based on selection of a user, smart TVs analyze and automatically provide content customized to desires of the user.

Meanwhile, when peripheral devices such as a set-top box, a Blue-ray disc player, a digital versatile disk (DVD) player, a streaming device, a home theater, an audio device, etc., are connected to an image display device such as a TV, various connected devices may be controlled by one remote controller by using a multi-brand remote (MBR) control function of a TV remote controller. The TV remote controller may generate an infrared (IR) signal for a peripheral device that is manipulated in an IR to automatically set the MBR control function of the TV remote controller according to whether the peripheral device is manipulated based on the generated IR signal.

However, to set the MBR function for a peripheral device manipulated in a wireless communication such as ZigBee RF4CE, Bluetooth, etc., a pairing process for wireless communication between the TV remote controller and the peripheral device is needed, but a user may have difficulty identifying a peripheral device to be connected because the TV remote controller does not generally include a display and most TV viewers are located at long distances from the peripheral device. As a result, it is difficult to equally apply a pairing technique for wireless communication between mobile phones and wireless devices, mainly headphones/earphones supporting Bluetooth.

Alternatively, the computer program product may include a S/W program itself, which is transmitted from the server to the client device or the third device or transmitted from the third device to client device.

In this case, one of the server, the client device, and the third device may execute the computer program product to perform the method according to the embodiments of the disclosure. Alternatively, two or more of the server, the client device, and the third device may execute the computer program product to execute the method according to the embodiments of the disclosure in a distributed manner.

For example, a server (e.g., a cloud server or Al server, etc.) may execute a computer program product stored in the server to control the client device communicating with the server to perform the method according to the embodiments of the disclosure.

The image display device according to an embodiment of the disclosure may make it convenient to set an MBR controller for controlling a peripheral device using ZigBee RF4CE.

While the disclosure has been shown and described with reference to certain example embodiments of the disclosure, the scope of the disclosure is not limited to the description and also includes various modifications and improvements made by those of ordinary skill in the art using the concept of the disclosure defined in the appended claims. 

What is claimed is:

 2. The image display device of claim 1, wherein the predefined input includes input for a key or a button included in the external control device.
 3. The image display device of claim 1, wherein the guide screen includes at least one item indicating at least one key included in the external control device, and indicates the at least one function corresponding to the external device and assigned to the at least one key.
 4. The image display device of claim 3, wherein the at least one item includes a first item indicating a first key included in the external control device, and a second item indicating a second key included in the external control device, and wherein the guide screen includes a first text indicating that a first function is assigned to the first item and a second text indicating that a second function is assigned to the second item.
 5. The image display device of claim 1, wherein the processor by executing the at least one instruction stored in the memory is further configured to control to display a message indicating that the image display device operates in an external device control mode.
 6. The image display device of claim 1, wherein the processor by executing the at least one instruction stored in the memory is further configured to control to display a broadcasting content while operating in an external device control mode.
 7. The image display device of claim 1, wherein the device identification information comprises at least one of a manufacturer, an operator name, or a model name of the external device.
 8. The image display device of claim 1, wherein the memory comprises a database storing in association the device identification information, the search data, the pairing data, and the control code information, which correspond to each of a plurality of external devices.
 9. The image display device of claim 1, further comprising a display, wherein the processor by executing the at least one instruction stored in the memory is further configured to: control the display to display an image based on an image signal received from the external device; extract identification code data by analyzing the image signal; and control the wireless communicator to transmit the identification code data to the external control device or the external device.
 10. The image display device of claim 9, wherein the identification code data comprises data used for authentication during pairing between the external control device and the external device.
 11. A method operating an image display device, the method comprising: obtaining device identification information corresponding to an external device connected to the image display device; transmitting, to an external control device, search data for the external control device to perform a discovering process for discovering the external device based on the device identification information; based on the external device being discovered by the external control device using the search data, transmitting, to the external control device, pairing data for the external control device to perform a pairing with the external device, and control code information corresponding to the external device; and in response to a predefined input being received from the external control device, displaying a guide screen corresponding to the external device, wherein the guide screen guides to execute at least one function of the external device using the external control device.
 12. The method of claim 11, wherein the predefined input includes input for a key or a button included in the external control device.
 13. The method of claim 11, wherein the guide screen includes at least one item indicating at least one key included in the external control device, and indicates the at least one function corresponding to the external device and assigned to the at least one key.
 14. The method of claim 13, wherein the at least one item includes a first item indicating a first key included in the external control device, and a second item indicating a second key included in the external control device, and wherein the guide screen includes a first text indicating that a first function is assigned to the first item and a second text indicating that a second function is assigned to the second item.
 15. The method of claim 11, further comprising: displaying a message indicating that the image display device operates in an external device control mode.
 16. The method of claim 11, further comprising: displaying a broadcasting content while operating in an external device control mode.
